what is one biological use of an isotope? and what is it?
isotope is the difference in valence electrons and the isotope can be used for cell dating
an isotope is a difference in the number of neutrons. one use for an isotope is to kill cancer tissue.
proteins are made up of C,H,O and amino acids, their function is and an example is dNA
on the ph scale, water is acid, because of its polarity
neutral, because the pos h and neg o( acid, because of its polarity, neutral, because the pos h and neg o ), and why?
what process is this?
the location of the dark reaction in a cell
crenation of a cell is caused by a hypotonic solution

experimental group receives what?
what is a community?
group of single species in an area
group of populations in the area
what is the placebo affect?
patients get better from non treatment
patients believe they're getting better so they feel better
photosynthesis is a transformation of solar energy into chemical energy stored in the bonds of proteins
what is osmosis
movement of water
permeability of water
polarity of water
hypertonic- having more solution than solute
is the addition of a phosphate group to a protein or other organic molecule

regulation is the use of positive and negative feedback mechanisms
taxonomy is the
which is not a step of natural selection
Varistion exists in every population
many species evolve from a single species
Environment is constantly changing
which is not a characteristic of the kingdom, Monera?
the five kingdoms are monera, protozoa, fungi, animal, plantae

cohesion and adhesion
hydrolysis and dehydration synthesis
amino acids are bonded together by
hormones like insulin
nucleic acids denature in inopportune temps or ph
what is the difference between an experimental group and a controlled?
controlled receives placebo and experimental receives treatment
controlled receives treatment and experimental receives placebo
the three ways to improve an experiment are to increase the sample size, repeat without making any changes and decrease bias by operating a double blind study.
breaking bonds energy
the formula for cellular respiration is; glucose +6O2 ------> 6h2o+ 6co2
hydrolysis is the to separate molecules, and dehydration synthesis is the to create more complex molecules.
Ribosomes make or create proteins
Nuclear membrane surrounds the nucleus and allows for the passage of DNA
rough endoplasmic reticulum synthesizes proteins
cell membrane is permeable, only hydrophilic and contains proteins
golgi body packages and distributes
vacuoles and vesicles transport, store and protect the cell. plants use it for water holding for photosynthesis
lysosome digest foods, organelles, and cells
